BUILDING-MATERIAL-HANDLING APPARATUS.

Application filed. February 2, 1925.

This invention relates to improvements in apparatus for handling building material and particularly for elevating and distributing material used in the construction of buildings, especially those constructed of reinforced concrete. 'lthas particular reference to that type of apparatus wherein there is provided a mast or tower adapted to support a chute or chutes for delivering concrete or like material by gravity to the point desired and which mast or tower is provided with an elevating bucket for raising the material to the desired height for delivery to the chute. In the construction work in which this type of apparatus is used there is also the necessity for elevating various kinds of building material which could not be handled by the concrete hoisting bucket and my present invention includes means whereby a material hoisting platform may also be supported and operated upon the mast without in any way interfering with the hoisting and deliver ing ofthe concrete and at the same time so balance the Various apparatus on the mast that the mast itself will be relieved of twisting and unbalancing strains.

For the purpose of disclosing the invention, one embodiment thereof is illustrated in the accompanying drawings in which Fig. 1 is a side elevation of an apparatus embodying my invention; 3

Fig. 2 is a front elevation thereof;

Fig. 3 is a detail cross section on the line 33 of Fig. 1;

Fig. 4 is a detail cross section on the line 44: of Fig. 1;

Fig. 5 isan enlarged detail of the side elevation showing more particularly the construction of the delivery apparatus;

Fig. 6 is a similar enlarged detail front elevation, and

Fig. 7 is a detail view of the tripping mechanism.

In the construction illustrated the mast or tower 1 comprises four corner posts which are preferably formed of angle iron and are secured in position by diagonal braces which connect the posts together. There are also provided on the interior of the mast suitable gusset plates 2 for bracing and tying the four corner posts together. These plates however arranged to Serial No. 6,266.

leave a clear cable passagewaythrough the interior of the mast for a purpose more fully hereinafter described. At a suitable elevation on the mast, depending upon the height-of the point at which it is desired to deliver concrete, which elevation in practice is generally about two stories higher than the working point on the building to which it is desired to deliver material, there is provided a head frame 3 which'is disposed on one side of the mast and supports at its lower end a chute hopper 4L in such a position that the hopper is at one side of the mast but in a position to receive the material from the hopper bottom hoisting bucket 5. This bucket is provided with a side delivery mouth 6 closed by a pivoted gate 7 and is adapted to deliver its contents into the chute hopper 4:, a bridge pan 8 being provided for bridging the space between the delivery endof the bucket and hopper. This bridge pan is supported on suitable links 9 pivotally connected to the bridge pan and'pivotally connected to the hopper to permit thebridge pan to move under the delivery mouth of the bucket when the bucket is in delivery position and out of the path of the bucket as it is ascending and descending.

The bucket is mounted on a traveling carriage 10 which travels vertically on the mast, being provided at its lower endwith a pair of rollers or wheels 11 bearingon the front face of two of the corner posts of the mast. and atits'upper end with a pair of rollers or wheels 12 engaging be hind the front posts of the mast so that the frame and bucket will be guided in their vertical movement. noted is on that side of the mast which may The bucket it willv be I be termed the outside, that is, it is on the controlled by a lever 18 pivotally mounted on one side of the bucket-and having one end connected by a link 19 with the gate. The opposite end of the lever is adapted to engage, when the bueketreaches its delivery position with an adjustable stop 20 secured on the head frame and arranged to project into the path of the lever. This stop 20 is provided with a plurality of bolt openings vertically spaced apart and slightly oif' the horizontal .center of the plate or stop 20. By this arrangement the height of the stop may be --v aried to .varythe opening of "the gate, the opening of the gate being at-the minimum with tlieplate at its highest position and at its maximum with the'plate lowered to its lowest position. By arrangingthe openings off center the plate may be turned up side downto get a wider variation intheo'pening distanceo fythe gate with a minimum sized stop plate. In addition tothe stop plate fill-also providea tripping arm 2lpivotallymounted so that normally when engaged by the lever 18 it will not operate the lever. However, if at any time it is desired to lopen the bucket gate to its fullest extent when the bucket is in its raised position, thee-rm may be drawn downwardly by an operating cableQQ and as 'the arm is in engagement with the lever 1-8 with the bucket in its raised position the gatemay-beopened -to its fullest" extent.

The bridge pan '8 is automatically moved to receiving position by an operating arm or lever adapted to project into the path of the bucketand pivotal ly mounted at its opposite end. This lever is connected :bya link rod 2% with 'thebridge pan so that when the free end of the =lever is engaged by :the side of the bucket as it vascends to delivery position the bridge pan will *be projected beneath the dejliveryjinouth of the bucket.

Unthe rear or inside face o f the mast there is provided a bracket .on which is pivotal-1y supported one end of a chute 26. This "chute is preferably provided .on its under face with a pivot pin socketed in a suitable socket on the bracket so that the chute may be swungon this pivot to various positions. Theouter end of the chute is supported by a boom line 27 which extends from the outer end of the chute to a brittle bracket 28 secured a point on the mast above the bracket and preferably near the top of the mast. As the bucket dand' chute hopper K1- are mounted on the front of the mast and have a side or transverse delivery and the conveyor is .mounted on the rear of the mast with its receiving hop-per 29 is proximity to the mast, there is provided for conveyin the material from the chute hopper :5to tlie delivery lehute 26, a conveyorchute 30 the spout of which extendsto directly over the 'ihopper'29 and the receiving end which is preferably provided with a receiving hopper 31. supported beneaththe delivery end of .the chute hopper 4. This conveyor chute is preferably supported at its upper or receiving end from the chute hopper by a suitable hanger bolt secured in an angle bracket fastened on one side of the chute hopper 4.

It is obvious that .the chute 26 may be extended by adding additional sections as 32 so that the material may be delivered to any point desired.

For conveying additional material for use #in construct-ion operations I provide a hoisting platform 83 which travels .on the inner face ofrthe mast. Due to the fact that the upper end of the chute 26 is supported at a point considerably higher than the working point onthe building there is ample free space below the bracket 25 to permit the hoisting platform to be ;raised to the highest working point on the building. This hoisting platform is preferably sup ported from a vertically traveling carriage 34 provided at its lowerend with a pair of rollers or wheels 35 beaningon :the front face of .the two inside angle .posts of the mast and at its upper .end with a pair of wlmels or rollers 36 engaging behind the angles of the inside posts of the m astso that the frame will be guided in its vertical movement. The platform raised and loweredzbyineans of a cable :37 passing upwardly and over a sheave 38 supported in .the mast cap 15 and thence downwardly .on ,the interior of the mast ilZO a bottom sheave 39 and thence to a drum on the hoisting engine '17. It will be noted that by passing the Cables con trolling the hoisting bucket and hoisting platform down through the hollow mast Iarnpile clearance for the operation of these cables is provided without interference with the operation of the concrete chutes and .delivery apparatus. Furthermore, due to the placing of the ,platrt'onm on the inside face of the mast it is readily accessible from the building to permit the loading or indeedring of theaplatforni and by placing the bucket on the outside face of the mast the .mast is not subject to imbalancing strains. Furthenmore, in this .construci'on the head frame bein moan e e if the mast on the in de fac balancing effect is ,obta, '1

The mast is capable of being built to various heights and to this end it .1 made in sections. the various sections being adapted to be connected tog-tether by suit blc joint plates 40. lY-hen the mast has built up beyond a predetermined point it becomes advisable to provide -,additional bracing, therefore to this end I provide an intermediate gu-y arm 41 which is adapted :to extend through the mast and be secured thereto and is provided with guy shackles material comprising a mast having an unobstructed passageway through the center thereof, a chute hopper carried by said mast on one side thereof projecting beyond the vertical plane 0 t said side and having its delivery end extending toward and beyond the edge of said side and an elevator bucket carried on said mast on the same side as said chute hopper, the tace of said mast between the chute hopper and the base of the mast being tree and unobstructed to permit the vertical travel of said elevator bucket on the mast and to the chute hopper, a delivery chute carried on the opposite side of said mast, a transfer chute extending between said chute hopper and delivery chute and arranged exteriorly or the mast, said delivery chute being supported at a point above the working point on the building with which the apparatus is associated, a material elevator carried on the same side of said mast as the delivery chute, the face of said mast being free and unobstructed between the support for the delivery chute and the delivery chute and the base oi the mast to permit vertical travel of the material elevator and cables for operating said bucket and elevator passing upwardly on the "face of the mast and downwardly through the center passageway in the mast.

In witness whereof, we have hereunto set our hands at Indianapolis, Indiana, this I L day of January, A. D. one thousand nine hundred and twenty five.
